On Wednesday, former Gov. John Baldacci and Rep. Mike Michaud picked up petitions from the Secretary of State?s office in anticipation of running for Senate.

Michaud?s chief of staff tells News 8 that the congressman hasn?t officially decided that he will seek Snowe?s seat.

A spokesman for Baldacci says that the former governor hasn?t officially committed to the race either.

Prior to Snowe?s Tuesday afternoon announcement, four Democrats had announced campaigns to unseat her: state Sen. Cynthia Dill, state Rep. John Hinck, former Secretary of State Matthew Dunlap, and builder Benjamin Pollard.

Republican Scott D?Amboise had launched a primary challenge against Snowe.

On Tuesday evening, Rep. Chellie Pingree said she is considering a run for Snowe?s Senate seat; she had not picked up petitions as of Wednesday afternoon.

Former Gov. Angus King tells News 8 that he is considering running for U.S. Senate.

A staffer who works with 2010 gubernatorial candidate Eliot Cutler says Cutler is also weighing a run.

A spokeswoman for Gov. Paul LePage says he is not running for federal office.

A spokeswoman for Secretary of State Charles Summers says Summer is considering a run for Senate.

Much of the political news over the next few weeks will be determined by whether Pingree and Michaud make serious runs at Snowe?s seat.

Several lawmakers picked up petitions on Wednesday to run for Maine?s Congressional seats.
